Indispensable for a quick battery check: the compact battery indicator Dometic PerfectCharge BI 01 is designed for intuitive one-button operation. It has a dedicated output for the Dometic battery chargers MCP 1204 and MCP 1207. Four LEDs indicate the charging condition of the connected lead acid battery in 25 % steps. The battery indicator can be permanently fitted in the vehicle or used as a mobile tool, e.g. to check the batteries of exhibition vehicles or seasonal vehicles.
